American Sign Language (ASL) is the main sign language commonly used in the United States and parts of Canada. British Sign Language (BSL) is the main sign language used across the United Kingdom. Around 250,000 to 500,000 people use ASL. While about 151,000 people use BSL. Understanding the difference between ASL and BSL can help learners choose the right language.
Both languages use signs to help people talk. But they are not the same. They use different hand shapes, grammar, and sentence order. Many common signs also look very different. Each language shows its own culture and history. So, the way people think and speak through signs can change.Â
Let’s dive into knowing what the main difference between these two sign languages is.
Why Do People Often Think All Sign Languages are The Same?
People often think all signers use the same gestures worldwide. Actually, this is a very common mistake for many learners. The comparison between ASL and BSL is actually quite massive. Both systems were developed in different countries over many years. But they use unique rules for your hands.Â
An American signer and a British signer cannot easily understand each other. They only share a few similar signs. Both languages use different grammar and rules. They also come from different cultures. So, they do not work in the same way. You should treat them as two separate languages. Each one has its own history and identity. Learning this helps us respect Deaf communities more.
How Did the History of These Two Languages Begin?
History explains why these systems look so different to the eyes. Thomas Braidwood opened a school in Scotland way back in 1760. Then, his family shared these signs across the whole United Kingdom. But a man named Thomas Gallaudet wanted help for Americans later. He visited London to find teachers for his new school project.Â
The surprising thing is that the British schools refused to share secrets. Instead, Gallaudet went to France to find a better teacher. Actually, he met a man named Laurent Clerc in Paris. They brought French signs back to America and started a school. So, ASL actually follows a French style of signing today. Similarly, BSL stayed independent and grew its own unique British way.Â
Why Do the Hand Alphabets Look So Different?
The main difference starts with the alphabet. ASL uses one hand for every letter, which makes spelling quick and simple. In contrast, BSL uses two hands for most letters. Because of this, the two alphabets look very different. Learning the correct alphabet helps you communicate more clearly with local sign language users.
- ASL uses a one-handed alphabet for spelling out names.
- BSL requires two hands for most letters and vowels.
- The two systems share very little vocabulary.
- British signers use their palms for vowels.
- American signers use one hand for the whole alphabet.

What is the Main Difference Between ASL and BSL?
Location is the main difference that separates ASL and BSL today. People who live in the UK use British Sign Language for communication. Actually, the government gave BSL official status back in 2003. Specifically, you will see BSL interpreters on many British news shows. Also, local schools and hospitals provide support for this system. But ASL dominates the scene in the United States and Canada.Â
To be honest, millions of people study ASL in American colleges. So, your choice of language depends on where you live. Anyway, each group has its own special jokes and traditions. Overall, these differences make every community very proud and strong. You should stick to the system used in your own city.
How Many Sign Languages Exist Across the Whole World?
Experts say the world contains hundreds of unique signing systems. Actually, people often ask how many sign languages there are globally. Currently, researchers track over 300 different types of sign language. Every country usually develops its own distinctive way of speaking.Â
But Australian signers use a system very close to BSL. The unexpected thing is that this happened because of shared history. Also, Japanese Sign Language is completely different from Chinese Sign Language. So, you cannot use one language to talk to everyone everywhere.Â
Honestly, these languages continue to change and grow much larger today. Truthfully, technology helps us find new signing systems in remote places. This diversity shows the amazing creativity of the human mind.Â
Why Did ASL Follow French Styles Instead of British?
ASL developed from French Sign Language, thanks to Gallaudet and Laurent Clerc. ASL shares many signs with French Sign Language, while BSL developed separately in the UK. Because of this, American and British signers cannot easily understand each other. So, history plays a big role in how both languages look and work.
- French Sign Language is the parent of ASL.
- British Sign Language grew without help from France.
- Gallaudet brought Laurent Clerc to America in 1817.
- ASL and French Sign Language look very similar.
- BSL remains independent of European signing styles.
Why is the Difference Between ASL and BSL Important for Grammar?
Sentence rules show another major factor between ASL and BSL grammar. Both languages ignore the order of spoken English words entirely. Actually, ASL users often follow a “Topic-Comment” style for sentences. This means you sign the main subject before the action. But BSL uses its own unique logic for spatial mapping.Â
Specifically, you place objects in the air to set scenes. Honestly, your eyebrows act like punctuation marks for every single sign. Also, the position of your body shows who is currently speaking. So, you must learn to think visually for every conversation. Anyway, mastering the grammar takes a lot of regular practice time. This visual logic makes these languages very powerful and fast.Â
How Do Numbers Change Between These Two Systems?
Counting looks very unique in these two sign languages. Actually, the difference in sign language includes specific number shapes. ASL signers count to ten using only one hand. They face their palm inward for the first five digits. Then, they flip their hand outward for numbers six through nine. But BSL users often use both hands for larger amounts.Â
People usually show numbers from one to five on one hand. After that, they use the second hand to show bigger numbers clearly. So, you should learn the local way of counting with fingers. If you use the wrong hand signs, small mistakes can happen. It helps to practise in front of a mirror every day. Slowly, your hands will learn the correct shapes and patterns.
What Kind of Experience Does an ASL User Have?
People in North America and Canada use ASL every day. The ASL vs BSL differences mean ASL signs will not work well in the UK. ASL has a rich Deaf culture and a large community. Many people also see ASL in media and TV today. However, each country keeps its own sign language system. So, learners must understand these differences before using it abroad.Â
- ASL is commonly used in the USA and Canada.
- The language uses one-handed counting and spelling.
- ASL users have their own unique cultural traditions.
- Most American colleges teach ASL to hearing students.
- Television shows in America often feature ASL signers.
How Does British Sign Language VS ASL Handle Names?
Spelling names involves different hand counts in both systems. At first, BSL spelling looks more active to observers. It requires both hands to work together for every letter. But BSL vs ASL fingerspelling uses one hand only in America. This style allows ASL users to sign while moving quickly. Actually, the difference between BSL and ASL spelling is very clear.Â
Truthfully, both languages use spelling for new English words. Also, signers often give each other special sign names. This sign represents your personality without spelling your whole name. So, you only spell things when a sign is missing. Anyway, mastering the alphabet is a very important first step. Practise your hand shapes every morning to stay sharp.Â
What Different Signing Categories Can You Study?
Researchers identify different types of sign languages. ASL and BSL are natural languages with their own grammar and history. In contrast, some systems follow spoken English word order for learning. Tactile signing helps Deafblind people feel communication through touch. International Sign supports communication at global events. Each system serves a different need.
- Primary sign languages are natural and full.
- Tactile signing helps people who are Deaf-blind.
- Manually coded English follows spoken word order.
- International Sign is a tool for global meetings.
- Home signs are gestures used within small families.

Why Should Immigrants Learn the Local British System?
Living in the UK makes BSL the best choice. Actually, the difference between ASL and BSL matters for your social life. Most Deaf people in Britain only use the British system. So, ASL skills will not help you during local meetings. But BSL is the primary language for UK schools now. Also, the government officially recognised BSL as a language.Â
Truthfully, learning local signs helps you find many new friends. So, you will feel more at home in your community. Anyway, focusing on BSL ensures that people understand you daily.

Then, you can practise your hand shapes with new friends. But you must stay consistent with your practice every week. Also, watching videos online helps you see the signs clearly.Â
So, do not be afraid to make small mistakes daily. Truthfully, native signers are very happy to help new students learn. Anyway, picking up a few signs each day builds confidence. Overall, you will discover a whole new way of talking. Start today and enjoy the beauty of visual talk.Â
Final Thoughts
Understanding the difference between ASL and BSL helps you see that sign languages are not universal. While both support clear communication, they use different signs, grammar and language structures. Each language also reflects the culture and history of its community. Therefore, choosing the right sign language depends on where you live and who you communicate with. Learning either language can build valuable skills and help you connect with more people.
